This ejection operation includes opening the mold ejector groove to remove the solid finished product from the fixture, and The tool is refilled with resin. As will be described in more detail below, the rotation speed of the kneading rod during the measurement process is to make the stalk rotate at the highest speed at the beginning of the measurement, and to decrease in a stepwise manner during the measurement process. In particular, it must be used einsteinium Or the quadratic function at the beginning of the metering process slows down the initial rotation (starting) of the yoke until the speed reaches a predetermined value Η. To achieve this, the starting operation must be slowed down until the speed reaches a predetermined value Η. This extension extends to The time interval of the predetermined value N also prolongs a molding cycle. In addition, during the calculation process, the rotation speed of the tappet must be determined stepwise according to the stroke, which is determined by considering the residence time of the resin. The position of the screw. Such a value of the rotation speed is cumbersome and disturbing, especially when the diameter of the rod must be changed. The number of revolutions must be calculated again. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economics The purpose is to provide a method for controlling the movement of the screw body, which can reduce the initial rotation of the element screw at the beginning of the metering process without prolonging the time required to reach the predetermined value N.

Fig. 5 is a graph showing the relationship between the rotation speed of the screw in the measurement process, and illustrates how to control the driving of the stem in the second embodiment of the present invention. Referring to the first lap, the construction of a motor-driven injection molding machine is shown. It includes an injection device driven by a reed motor. There is a text describing the use of M to promote the understanding of the present invention. The injection device converts the rotation of the servo motor into the linear motion of the ball screw and the female screw to rotate the screw. In the first plaque, the rotation of the axillary motor 11 is transmitted to the ball yoke 12. The nut 13 is fixed to the pressure plate 14 and it moves forward or backward in response to the rotation of the ball crocodile rod 12. The pressure plate 14 is rotatable along guide bars 15 and 16 fixed to a base (not shown). The stress plate 14 moves forward and backward to the bearing 17, the load unit 18, and the K-out shaft 19. The tappet 20 is mounted on the heated cylinder 21 and is rotatable and movable in the sleeve direction. The heating cylinder 21 corresponds to a funnel 22 at the rear of the yoke 20 for feeding resin. Screw rotation The rotation diameter of the servo motor 24 is transmitted to the injection sleeve 19 by a connecting member including a belt and a pulley. That is, the kneading rod 20 is rotated because the ejection sleeve 19 is rotated by the screw servo motor 24. During the plasticizing / metering process, the melted resin is stored in the head of the screw 20 in the heating cylinder 21, that is, it is stored on the ejection outlet side 2 when the screw 20 is turned backward in the heating circle 21. In the post-injection mold of the molten wax at the front end of the screw 20, the rod 20 is advanced in the heating cylinder 21 to form JS. The force acting on the tree wax is detected by the load unit 13 as a counterforce.

Description of the invention (b) This separation. Therefore, the melted resin at 20-2 is only about half the volume of the resin before melting. The compression part 20-2 is to reduce the space that the resin can pass through to make up for the reduced product. This allows the rod-shaped member 20 'to be tapered at a position corresponding to the compression portion 20-2 to make the spiral groove shallower. The compression part 20-2 presses the molten resin, which enhances the heat release effect by friction, and increases the pressure of the resin. The air, water vapor, volatile gases contained in the air and pollution in the resin are heated in the resin 21 The gas is pushed back into the funnel 22. It is clear from the above that the resin pressure in the heating cylinder 21 is the highest value at the compression portion 20-2. The rod-like member 20 'has a maximum diameter in a region corresponding to the measuring portion 20-3. The metering part 20-3 forms the shallowest suspected spiral groove on the bark piece 20 |. The resin is subjected to a large shear force at the metering portion 20-3 and an internal exothermic reaction of M is heated to a uniform temperature. A certain amount of resin is then fed to the injection nozzle side of the heating cylinder 21. The feeding of the molten resin from the metering portion 20-3 to the injection nozzle side is performed by a check valve ring 20-5 in the head 20-4. The check valve ring 20-5 is positioned in the circle near the left side during the metering process. In this state, the molten resin can escape from the most part 20-3 to the injection nozzle side. After the metering process is completed, the check valve ring 20-5 moves to the right in the figure due to the difference in scraping force. As a result, the resin is prevented from flowing back to the metering portion 20-3 from the injection nozzle side. The head 20-4 is generally formed separately from the rod 2 (Γ). The head 20-4 forms a male thread on its root. The end of the rod 20 'forms a female thread. The above-mentioned male media pattern is engaged with the female ridge pattern on the bark piece 20 ', so that the head 20-4 can be connected to the bar-shaped piece 20'.

Description of the invention (7) The diameter of the root of the head 20-4 is much smaller than that of the bark piece 20 '. With reference to 3A and 3B 豳, it will be explained how to determine the rotation speed of the kneading rod during the measurement process. Circle 3A shows the measurement position, that is, the rod position and the rod back pressure. On the other hand, the 3B display shows the measurement position and the rod rotation speed. Groups 3A and 3BB are one of the four-stage setting operations. Example: In the fourth stage of the setting, the first three stages are generally used to balance the slip of the resin. In this stage, the high-temperature resin is melted with a relatively high speed of the tappet and a low back pressure in the first half of the heating cylinder 21. During the melting process, the stopping time of the resin increases. The speed decreases in a stepwise manner. This is because the resin needs to increase the heat release due to the shear force when the back warm is increased. The fourth and final stage is to provide a ®SetM to improve the accuracy of the measurement value used at the beginning of the filling process. More specifically, Set a very low rotation speed M and a low back pressure value K to prevent the kneading rod from being overrun two or three millimeters before the measurement completion point, and to prevent the resin from flowing back. Obviously from the above, the screw 20 is in the measurement process. The rotation speed is the highest at the beginning of the measurement, and then decreases stepwise. Therefore, the head 20-4 of the screw 20 receives a large load at the beginning of the rotation of the stalk 20. This large load may damage the thread of the stern head 20-4. Part. The check valve ring 20-5 is almost in contact with the inner wall of the heating cylinder 21. Due to this, the screw 20 does not move at all at the beginning of the measurement. This means that the rotation of the screw 20 due to the check valve ring 20 -5 and plus The friction between the inner walls of round cymbals 21 causes local heating and generates heat. This heat has a negative effect on the resin. In this regard, a linear or quadratic function is used to reduce the size of the paper. The Chinese national standard (CNS) ) A4 specification (210 X 297 public love) --------- ------- Order I, III {Please read the unintentional matter on the back before filling this page) A7 416911 _______B7__ V. Invention Explanation (J) (Please read the precautions on the back before filling this page) At the beginning of the measurement process, the initial (starting) speed of the screw, M reaches the predetermined speed of the measurement start Η. However, the start operation must be slowed down until the speed reaches the predetermined value K. It extends the time interval before reaching the predetermined value Η, and then, it also extends the time of one molding cycle. What's more, the rotational speed of the susceptor 20 during the measurement process must be determined stepwise in accordance with the stroke. That is, when the stop time of the most tree shrew is measured, it is determined according to the position of the stick 20. The large value of the rotation speed is numb, because when the diameter of the screw 20 must be changed, how many values must be set. With reference to the fourth plaque, the method of controlling the driving of the kneading rod in the first embodiment of the present invention will be described. This method can be applied to a threshold-driven motor as described in Section 1 (a), which clamps a motor-driven injection device. However, according to this example, the control operation achieved by the controller 26 is different from that obtained by the conventional injection device. The following description will be made with reference to laps 1, 2A and 2B 臞, M and lap 4. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. When implementing the method of controlling the joy of this embodiment, the operator must set a value (rotation speed) in the controller 26. Rotating speed. The controller 26 performs a one-time operation to rotate the stick 20 at a low acceleration A1 until the kneading stick 20 speed reaches a value (speed) Hk. The speed Nk is defined as a predetermined ratio value K relative to the speed N. After the rotation speed of the stalk 20 reaches the rotation speed Hk, the controller 26 performs a control operation to make the stalk 20 rotate at an acceleration A2 until the rotation speed of the stalk 20 reaches Η. The value of the acceleration A2 is larger than the acceleration A1. Except that, the ratio K is determined so that the rotation speed Hk with which it is associated does not cause a sudden load of marinating and adding to the head 20-4 of the screw 20, which may cause damage. In particular, in this embodiment, the controller 26 uses a predetermined speed Η to calculate -1 〇- This paper size is applicable to the Chinese National Standard < CNS) A4 specification (210 X 297 mm) Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 416911 a7 _B7 V. Description of the invention (?) The time T1 required from the start of the measurement process to the speed of the rotation reaching Nk. The controller 26 controls the yoke rotation motor 24M to ensure that the yam 20 is rotated from the M acceleration A1 within the time T1 when calculated. Then, the controller 26 calculates the time interval T2 from when the rotation speed reaches Nk until the rotation speed reaches Η. When the rotation speed of the yoke 20 reaches Nk, the controller 26 moves to control the yaw shaft to rotate the limb motor 24 to ensure that the dart bar 20 rotates at the M acceleration A2 within the calculated time T2. The rotation of the yoke is generally gradual at the time of starting, so no significant load is added to the yoke 20-4. This is similar to the case where a kick effect can be obtained during starting operation. In the time interval from the rotation speed Nk to the rotation speed 加速度, the acceleration A2 at the start of the stalk is much larger than the acceleration A1. Therefore, the time required to reach the rotation speed K is not very long. Furthermore, the movement of the screw is started when the acceleration A2 is started. Therefore, no local heating occurs, which is caused by friction between the check valve ring 20-5 and the inner wall of the heating cymbal 21 later. This implication means that any negative effects due to local heating can be avoided. As described above, according to this embodiment, at the beginning of the metering process, the screw is started only by setting the predetermined value N of the yoke speed and has an automatic buffering effect, thus eliminating any damage to the head and negative local heating. Referring to Fig. 5, a method for controlling the driving of the stalks according to the second embodiment of the present invention will be described. This method can be applied in conjunction with Section 1 to describe a servo motor to drive a motor-driven injection device. However, in the case where the K-type control method is applied to the injection device shown in Fig. 1, the control effect achieved by the controller 2B is different from that achieved by the conventional injection device. The following description will refer to Figures 2A and 2B, M and 5-11.

The controller 26 uses the predetermined speed values Hs and HeW and the position detection value sent from the address detector 27 key between the start of the measurement process and the end to correct the speed of the stick 20. The controller 26 controls the shaft rotation motor 24 according to the correction value. More specifically, the controller 26 uses the nature correction shown by the fifth solid line in the rotation speed of the stick 20 according to the position detection value from the start of the calculation to the end of the stroke. That is, the position detection value is based on The predetermined rotation speed values Ns and Ne of the start and end of the stroke are measured, respectively. The position of Ss and Se is determined by the current stick position. At the beginning of the measurement g stroke, the stalk position Ss is equivalent to the screw position at which the stalk 20 reaches the Ms value. Let the gauge in the situation shown in Figure 5 be X at the stalk position. After the stalk is corrected, the speed Y is as follows: Y = Ne + {(Ns-Ne) / (Se-Ss)} X (Se-X) Ministry of Economic Affairs The Intellectual Property Bureau employee consumer cooperative printed controller 26 may use the screw rotation speed value Hs until the position S1 between the stalk to the measurement position between the measurement start position Ss and the measurement end position Se, and then when the rod reaches the position S1, The controller can perform the modified control operation, as shown by the dotted line in FIG. 5. Position S1 is (Ss + Se) / 2, half of the fifth plaque printing process. In this case, the controller 26 can use the linearity of the screw rotation speed in the taper position X according to the Hs and He values K and the intermediate position (Ss + Se) / 2K and the screw position Se, as in the above-mentioned correction. Amended. The position reached by the rotation speed Hs is not limited to the intermediate position. It can be any other position obtained by proportioning according to the pre--12-size of this paper applicable to the National Solid Standard (CNS) A4 specification (210 X 297 mm) 416911 A7 B7 V. Description of the invention (U). In this embodiment, the two rotation speed values at the beginning and end of each measurement must also be determined and set as described above. If necessary, it is convenient to set the speed value and the required operation to change the set value. Although the above embodiment is described in conjunction with a motor-driven injection molding machine, the present invention can also be applied to a hydraulically-driven injection molding machine.
